STALL TEST The object of this test is to check the overall performance of the transmission and engine by measuring the maximum engine speeds at the "D" and "R" ranges. CAUTION: (a) Perform the test at normal operation fluid temperature (50 — 80°C or 122 — 176°F). (b) Do not continuously run this test longer than 5 seconds. MEASURE STALL SPEED (a) Chock the four wheels. (b) Mount an engine tachometer. (c) Fully apply the parking brake. (d) Step down strongly on the brake pedal with your left foot. (e) Start the engine. (f) Shift into "D" range. Step all the way down on the accelerator pedal with your right foot. Quickly read the highest engine rpm at this time. Stall speed: 2,100 ± 150 rpm (g) Perform the same test in "R" range. EVALUATION (a) If the engine speed is the same for both ranges but lower than specified value: • Engine output is insufficient. • Stator one-way clutch is not operating properly. NOTE: If more than 600 rpm below the specified value, the torque converter could be at fault. (b) If the stall speed in "D" range is higher than specified: • Line pressure too low • Front clutch slipping • One-way clutch No. 2 not operating properly • OD one-way clutch not operating properly (c) If the stall speed in "R" range is higher than specified: • Line pressure too low • Rear clutch slipping • Brake No. 3 slipping • OD one-way clutch not operating properly (d) If the stall speed in "R" and "D" range is higher than specified: • Line pressure too low • Improper fluid level • OD one-way clutch not operating properly
